Title: Bart Scholte Van Mast: Innovator in Substrate Processing Technologies

Introduction

Bart Scholte Van Mast is a notable inventor based in Azmoos, Switzerland. He has made significant contributions to the field of substrate processing, holding a total of 7 patents. His innovative approaches have advanced the methods used in various industrial applications.

Latest Patents

One of his latest patents is an apparatus and method for processing a substrate that displays out-gassing when placed in a vacuum. This method involves placing the substrate in a vacuum and performing an out-gassing treatment by heating the substrate to a specific temperature. The process continues until the out-gassing rate is determined by the diffusion of the substrate's contamination, establishing a steady state. Following this, the temperature is lowered to a level where the diffusion rate of the substrate's contamination is reduced, allowing for further processing until the substrate is covered with a film comprising a metal.

Another significant patent involves a method of magnetron sputtering and a method for determining a power modulation compensation function for a power supply applied to a magnetron sputtering source. This method includes rotating a magnet of a magnetron with an angular frequency and periodically modulating the power level applied to the source during the sputtering of material onto a substrate. This modulation includes a frequency that is a harmonic of the angular frequency of rotation, enhancing the efficiency of the sputtering process.

Career Highlights

Throughout his career, Bart has worked with prominent companies such as Oerlikon Balzers AG and Applied Materials, Inc. His experience in these organizations has allowed him to refine his skills and contribute to cutting-edge technologies in substrate processing.
